MANFOLDING ATTACHMENT FOR TYPEWRITERS.

Alipplieation filed June 2l, 1922. [Serial No. 569,8l.

T0 @ZZ whom t may concern.: y

Be it known that l, MALCOLM L. Cossrr'r. a citizen of the United States, residing at Alameda., in the county of Alameda and State of California, have invented certain new and useful. Improvements in Manifolding Attachments for Typewriters, of which the following is a specication.

All/l invention relates to that class ot manil@ folding attachments for typewriters in which one or more maniiolding members are carried by arms mounted on the platen carriage of the machine, and are adapted, by the movement of said arms, to be placed in and removed from functional position in the line of type impact; and more especially it relates to a form of 'such attachments in which the arms are carried by a plurality of independently' rotatable, nested sleeves` 2@ and the manifolding members are stored upon the attachment in such wise as to adapt them to be drawn out in successive lengths or sections for association with the arms, and presentation in the line of type impact.

The chief object of my present invention is to so combine the rotative nested sleeves, the stored manifolding members, andthe ribbon carrying arms, as to produce a compact structure in which the nested members are lrept down to practicable diameters, the storing housings and one set of arms being detachably litted to one end of the nested sleeves-whereby they may be removed readily and others substitutedas occasion requires.

To this end, my invention consists in the novel manifolding attachment for typewriters which l shall now fully describe by reference to the accompanying drawings, in which- Fig. l is a front elevation, partly broken, of my manifolding attachment.

Fig. 2 is a perspective view, enlarged, ot' the set of ribbon carrying` arms at the right hand end.

Fig. 8 is a left hand end elevation showing the arms elevated. l

Fig. is an elevation of F ig. 3, showing the arms depressed to functional position.

Fis: e is a section on the line (3*6 ot diminished diameters.

Fig. 8 is a perspective view of one ofthe storing housings for the manifolding ribbons, showing its detachable fitting to its carrying member.

Fig. 9 is a perspective detail of two of the nested carrying members..

Fig. l0 is a detail view or the locking device for the nested members, taken on the line l010 of Fig. 6.

l is the platen carriage or a typewriter and 2 is the platen. Secured upon the platen carriage, one nearpeach end, are the brackets 3. lln these brackets are journaled short shafts 3 with cranks 3..

Between the free extremities of the cranks 3 are carried the independently rotatable nested sleeves, the innermost, which may be a rod, as here shown, being designated by Il.,

the .middle one by fl andthe outermost At the right hand end'the sleeves carry the ribbon carrying arms 5, 5 and 5 respectively, F iffs. 'land 2, each arm having a stud'o which may indicate means .tor the manual or mechanical operation by which the arms are moved with the sleeves as axes to primarily carry their ribbons down to- Wards functional position.

At the left hand end, the sleeves project beyond their carrying bearing, to successively diderent distances, as seen clearly in Fig. 6, the innermost fr extending the longest distance and the outermost d extending the shortest distance.

The innermost sleeve on rod el carries at its extremity a housing 7, within which is fitted a rotatable spool 8 upon which is wound a manitolding ribbon '9.

rl'he middle sleeve sl carries'at its extremity a housing 7 with ay rotatable spool 8 and a maniolding ribbon 9.

ln similar manner the outermost sleeve t has a housing 7 with a rotatable spool 5 and ribbon 9".

Each housing is detachably fitted to its sleeve to rotate therewith, by' means ot' a spline l0 titting in a groove i"--Figs. ti, 8 and 9, yand said housings are ol successively l Fo the housings are secured the ribbon carrying arms ll, ll and 1l respectively, arms ettending in spaced relation over housing series,

provided with outwardly bent ends 12, in

which are ribbon guiding slots 12-l"igs. 5 and 7.

' Each housing has'on its periphery an angular slot 13-Fig. 8, through which the manifolding ribbon emerges-Fig 5. The ribbons thence extend along the arms 11, 11 and 11"--Figs. 5 and 6, andv through the slots 12 in the ends 12 of said arms and thence to the arms 5, 5 and 5 at the other ends of the sleeves, and through toothed slots 14 in said arms-Figs 1 and 2.

In operation, as is the case with manifolding attachments of this general nature, the ribbons are placed in and removed from functional position in the line of type impact, by swinging their carrying arms first with the sleeves as axes, and then upon the shafts 3 as an axis, as indicated in Figs. 3 and 4; and, as in forms of these attachments in which the ribbons are stored and 'are adapted to be drawn out in successive lengths to present fresh sections for use, as preceding ones are worn out, said ribbons are released from ,the teeth of the slots 14 in the carrying arms at the right and are drawn out from their spoolsl as needed and reengaged on said arms. But in the present construction, by carrying the spoolson the outside of the sleeves; these nested elements may be confined to practicable dimensions, and by carrying one set of ribbon arms on the spool assembly, it is possible to readily apply `the series of spools and one set of arms to the sleeves, and to remove them, for the sub stitution of fresh spools and their associated parts when the preceding ones have been exhausted, thus conducingto simplicity and economy.

In order to releas'ably lock the sleeves from movement, there is fitted over the journal bearing of the crank 3 at the left, a spring cap 15--Figs. 10 and 6, and in said journal under the cap is housed a locking ball 16, which is held down in resilient contact with sockets 17 in the several sleeves. The ball will hold the sleeves against accidental or inadvertentv movement, but it will yield to sufficient pressure to permit the sleeves to turn.

1. A manifold attachment for typewriters comprising a rotative member mounted on the platen carriage of the machine paral'el with the platen; an arm carried by said member at one end; a member fitted upon the other end of said rotative member; an arm carried by said fitted member; and a manifolding member carried by said fitted member and adapted to be drawn therefrom in successive lengths'for engagement by and between said opposing arms.

2. A manifolding attachment for typewriters comprising a rotative member mounted on the platen carriage of the machine, parallel with the platen; an arm carried by said member at one end; an apertured housing fitted upon the other end of said member; an arm carriedby said housing; and a'manifolding member within the housing and adapted to be drawn therefrom in successive lengths for engagement by and between said opposing arms. l

3.' A manifolding attachment for typewriters comprising a plurality of independentlyv rotative nested members, mounted on the platen carriage of the machine, parallel with the platen; an arm carried by each of said nested members at one end; a member fitted upon the other end of each of said nested members; an arm carri d by each of said fitted members, said spaced relation; and a manifolding member carried by each of said fitted members, and adapted to be drawn therefrom in successive lengths, for guidance by the spaced arms and to be engaged by and between said arms and the arms at the opposite end.

`4. A manifolding attachment for typewriters comprising a plurality of independently rotative nested members, mounted on the platen carriage of the machie, parallel with the platen; an arm carried by each of said nested members at one end; an apertured housing fitted upon the otherend of each of said nested members, said housings being of relatively decreasin diameters; an arm carried by eac of said housings and lying in spaced relation to each other; and a manifolding member carried by each of said fitted members, and adapted to be drawn therefrom in successive lengths, for guidance by the spaced arms and to be engaged by and between said arms and the armsy at the opposite end.

5. A manifolrling attachment for type writers comprising a plurality of independently rotative nested members mounted on the platen carriage of the machine, paralle'L with the platen; arms associated with each nested member at each end thereof; a manifoldin member carried by and between each pair o arms; a bearing in which said nested members are rotatively' mounted; a resilient cap fitted over said bearing; and a ball housed in the bearing under said cap and adapted by the pressure thereof to releasably engage each of said nested members.

In testimony whereof I have signed my name to this specification.
